I just got the same thing - and i was pretty sure it worked yesterday.

Ensure you have a connection interface up and running before using it and that error should disappear. There are currently no verified cases in which netdiscover does not work. If you continue to have problems post your computer details along with dmesg output.

I tried today again with my Ethernet Card, it works OK.
I was on the Wireless when I had problem, I will double check again tonight, and post my update later. TKS!

Nothing is wrong with Netdiscover, type:

netdiscover --help

Yes I agree with you, doesn't seem to be the problem of netdiscover.
I have issue running other programs from time to time, such as cannot connect my Wireless AP with wpa_supplicant, got error messages and I can solved the issue with Live CD reboot, it seems that live CD boot up sometimes doesn't load up all the necessary drivers. And the ettercap, when I repeat "scan for hosts", I will get different hosts results each time. This doesn't happen on the BT2.

My system is Toshiba Satellite M30, most of time I am on the wireless, but I will try the ethernet later, and give the feed back.

dmesg is too long to post, but below is my wireless card info
ipw2200: Intel(R) PRO/Wireless 2200/2915 Network Driver, 1.2.1dmprq

i have the same error... i'm on the wireless too and i use bt2.
libnet_init() falied: unknown physical layer type 0x321

only one difference is 0x321 with 0x323

I had tried with a pc connected to my router by ethernet and i didn't receive errors opening netdiscover...

Since no one has mentioned even using command line parameters to troubleshoot netdiscover, here are some things to try:

-i device: your network device

#Scan a class C network, to see wich hosts are up
netdiscover -i wlan0 -r 192.168.1.0/24

#Scanning /16 network, trying to find online boexes
netdiscover -i wlan0 -r 192.168.0.0/16

#Scan a class A network, trying to find network addresses
netdiscover -i wlan0 -r 10.0.0.0/8

#Auto scan common networks
netdiscover -i wlan0

#Dont send arp requests, listen only
netdiscover -i wlan0 -p

Just like PrairieFire said Nothing wrong with Netdiscover, I believe this after I tried on my Ethernet card.

When I run the Netdiscover on the Wireless, I don't always get error, most of time there is no problem (Command line or KDE menu). Even I got the error message, I can always reboot my LiveDVD and get Netdiscover to work again. So somehow I guess the problem is from either driver loading issue, or hardware compatibility issue. (And I sure there is no ISO DVD burning issue)
